. BUGKET-CATCI-I.

To all whom it may concern:

Be it known that I, WALKER STANSELL, a

citizen of the United States of America, re-

siding at Memphis, in the county of Shelby and State of Tennessee, have invented certain new and useful Improvements in Bucket-Catches, of which the following is a specification.

The present invention relates to an improved bucket catchiandis designedparticir larly for use in connection with overhead conveyers employing a bucket and supporting traveling carriage.

The primary object of the invention is to provide an improved releasing device to disengage the supported bucket from its carriage by a simple manipulation of a tripping mechanism that is in itself extremely simple in construction and operation, but accurate and efficient in performing its required functions.

The invention consists essentially in certain novel combinations and arrangements of parts of the bucket latch or catch and the tripping or releasing mechanism as will hereinafter appear.

In the accompanying drawings I have illustrated one complete example of the physical embodiment of my invention constructed according to the best mode I have so far devised for the practical application of the principles of the invention.

The drawing shows in perspective a traveling carriage supported upon a rope track, with the bucket suspended from the carriage, and for convenience of illustration parts of the devices are shown-broken away and some parts are shown in section.

In the exemplifying structure shown in the drawing I have utilized a well known type of traveling carriage comprising the frame 1 which is adapted to travel back and forth upon the rope track 2 by means of the sheaves 3, 3, 4, journaled in the frame and adapted to run on the rope or cable 2.

The bucket 5 is of conventional type and is hoisted to the carriage by means of the hoisting rope 6 having one endattached to the carriage at T and passing over the pulley 8 of the carriageandunder the sheave 9 of the bucket. When'the bucket is empty and returning for a load, it is directly supported from the carriage by means of a fixed, me-

tallic sleeve 10 which may be cast or wrought iron as required and is rigidly sup- Specification of L'etters Patent.

' ported and fixed by means of the transverse bars 11 11 thatare bolted to the lower frame bars of the carriage. This metallic sleeve is cylindrical and open at the top, but is provided with a lowerportion 12 which is completely around the inner bore of the sleeve, and the decreasing diameter of the flaring lower portion of the hollow member or sleeve terminates at this flange. A pair of yieldable arms or spring latch bars 14 15 are designed to co-act with the flanged sleeve. These two arms or latch bars are arranged vertically and parallel and are i joined by the angle plates 16 16 bolted thereto. At their lower ends these two bars are pivoted in the head 17 of a plate 18, which as clearly shown is bolted to the bucket, a bolt 19 and nut 20 being employed for this purpose. These latch bars also provide a bearing for the bolt 21 which forms the journal for the sheave 9 for the hoisting rope. At their free ends these latch bars are formed with heads or hooks 22, and the extreme ends of the hooks are beveled at 23 to form a cam or wedge surface. The latch bars from their point of connection at the angle plates 16' to their free ends are of resilient or yielding, springy, characteristic, and when properly acted on may be bent toward each other, to free the supported bucket from the carriage.

For the purpose of disengaging the hooks and releasing the bucket I employ a hollow metallic plunger 24, located within the upper open end of the sleeve and movable therein. This plunger is similar to an invertedcup and its lower annular edge is interiorly beveled at 26 to co-act with the beveled edges of the heads or hooks on the ends of the resilient latch bars 14, 15 to move the same toward each other. The plunger is actuated by a tripping lever 27 which is fulcrumed at 2.8 in the carriage frame and provided with a trip rope 29 within easy access of an operator. One end of the trip lever is pivoted by the bolt 30 in the slotted end 31 of a pivoted link 32. This link is pivoted 0n the bolt 33 supported transversely in the of the hollow plunger, and a spring 35 at- The operation of the device Will be understood from the drawing. The k u cl zet is revoluble, as shown by the arrows, on the e ee 22 Whie my lid are ved e ti e this motion is esirable in some instances to absorb strains.
